MMR920

This gauge pressure sensor is a pressure sensor IC utilizing MEMS technology. It combines a MEMS sensor with a Delta-Sigma (⊿Σ) AD converter to output high-precision pressure values digitally. I2C and SPI interfaces are available.

Outline

The MMR920 series is a Gauge pressure sensor module that includes a MEMS pressure die with a dedicated analog front end IC to provide a fully calibrated and temperature compensated digital output (I2C/SPI). Its unique packaging structure provides protection from aggressive media since electronics are not exposed to the high pressure port. The MMR920 series is ideal for low pressure application requiring high accuracy and robustness.
